Question about Audio Players & Recorders

Would changing the belt help as my turntable plays too fast.

Hello! I recently tried using my turntable and my turntable somehow started to spin faster then the 33LP speed and sounded like it was stuck on 45RPM somehow.I tried adjusting the speed using the screw adjustment but that did not work either.Would installing a new drive belt cure the problem or is there a way to slow the motor down somehow? Did the potentiometer somehow blow? If so i dont think i can repair it as i lack that skill in repair.Thank You to all who reply!!!

A lot of turntables have two belt positions on each pulley. One for 33 and one for 45. I would check to make sure the belt hasn't slipped into the 45 position.

    Greetings Jim and Thank You for the reply; How do i check to see what position the speed is and how do i correct it if it is not??? Thank Again! Best regards,Jim

    After doing more research on this table it looks like the speed control is electronically controlled rather than changing belt positions. It looks like there are a lot of other people on the internet complaining of the same problem with this turntable. It seems most recommend using switch cleaner on the speed switch. If this does work then you end up having to replace the motor or the IC board controlling the motor. Sorry it couldn't have been a simpler fix.

SOURCE: Cannot adjust speed on a vintage Technics SL-B30 Turntable

More than likely it is a faulty drive IC (Integrated Circuit). If so, your out of luck, because most parts for this unit are discontinued, with the exception of the belt.

There really isn't much else you can do. Will probably cost too much to repair, if you can find someone who can repair it.

Sorry couldn't be of much more help.

I suspect that a fault has occured on the section that controls the speed of the motor. Perhaps an IC failure. If you have a look at any of the IC's on the motor board you could note down the numbers and look around on the net to see if they might give you clues to what they do, plus what they cost to replace or if they are obselete.

How do I fix the speed of my Jensen JTA-460 turntable? I've tried numerous records that previously worked perfectly, but now the speed is too slow regardless of what album I try.


Could be the belt for the pulleys is stretched a little, or there is something making it slip, or the potentiometers were set incorrectly from the factory . It is normal to have one for each speed. It is unknown if you can access these from the bottom of the unit. Slippage is less likely to be caused by something oily, since it would alternate the speed faster and slower and yours seems to have worked then reached a constant slower speed. Do your 45's and 78's play ok? (yeah I know, does anyone have a lot of 78's on hand)
Your model does not have an outside pitch control to fine tune the speed faster or slower. Another Jensen model JTA-230 does. Entry level turntables such as yours are not speed accurate reliable. After reading reviews on your turntable, it's possible that the belt is the problem. If the slow speed problem had happened from the start, it would be safe to say that the speed wasn't calibrated correctly and you could have returned it and perhaps had better luck with another one but because it worked fine at the start and then now plays slower, it's either the belt or the potentiometer for the 33rpm speed has somehow changed.

HELP: Stopped spinning


It's likely the belt has slipped of and probably needs replacing. You can do this yourself. It will be found under the turntable matt. The trick though is fitting it back on. But you might find the instructions on-line (enter the model number into google search). Some people have even put YouTube video's on how to replace the belt on popular turntables.

Turntable doesn't play


If the turntable stopped spinning then then the turntable belt maybe broken or has slipped off the drive.

The turn table is going round but its playing the record to fast the speed seems wrong


Hello!
are you sure, that your speed selector is on 33.3rpm, not 45?
assume, it's in correct speed settings. do you know, that across the ocean power grid AC frequency is 50hz, in US it's 60hz. Means: ac motor will spin faster, than it should. If you bought this unit abroad, that's where is your problem at. some expensive units have 50/60hz pulleys switch, some not. Especially, if it's DC or direct drive motor. Check your owner's manual for specifications. May be you find an answer. If not, there is a problem with motor's regulator, which is built in(DC motor). Turntable is a belt driven. If you won't find 50/60hz adjustments, take it to repair shop.
Good luck,
Alex.

Platter/motor won't turn


I don't know the answer, but you have written one of the finest, most comprehensive problem descriptions I have come across. In mechanical scenarios, that is priceless. I'm sure a turntable guru will see it and go, "aw. I know what that is". Good Luck.

Turntable spinning too fast


The turntable speed is controlled by a belt, which is virtually a big rubber band. If it spinning too fast , then this means the belt is too tight. The only way this can happen is for the unit to be fitted with an incorrect size belt. You didn't say if you have a new unit, or a second-hand one, or if it has recently had the belt replaced. If it is a new unit and still under warranty, take it back to the retailer and ask them to fix it for you. Again, if you have recently had the belt replaced, take it back and ask them to do the job again, and this time to please use the correct belt. Be polite but firm....If you are a handyman, the job is not too hard to do yourself, and if you need any extra help, just ask, johnatwagga@yahoo.com. To buy the correct belt, you will need the name, model number, and preferably, the serial number. All of these can be found on the back of the unit. Good luck, and I hope this helps.
